clutch drag

(1/2) > >>

david451:
my cb 750k 1974 is dragging the clutch a bit, been looking at the threads and it seems to be a common fault.

I have adjusted the lever inside the casing and changed the cable but although all the parts are moving properly it still drags a bit. I have been riding it about and perhaps its just me being fussy but I cant adjust the cable leaving a little slack it needs adjusted up. but it doesn't slip.

I have memories of my 250 back in the 70s doing the same thing.

is this something that's normal on these old bikes, but  if not any advice before I pull the plates out. phew one step forwards and two back.

Bitsa (Ralph Wright - RIP):
Both my 35 year plus CB750,s don't do that and still on original plates etc so NO.In the past I have discovered synthetic don't help many will disagree though as usual
Cheers

Trigger:
+1 with Bitsa on this one, modern oil does not help. Most modern bikes have a oil jet that sprays over the clutch basket, were the old girl's clutch is running in oil.

Waggles:
My F1s clutch plates tend to stick together when left so initially I have to wait a bit for the clutch to stop rattling before engaging first  :) apart from that I get no drag. Not using synthetic oils.

What are your symptoms exactly?

Using motul 10/40 semi but I get a drag on the clutch on my cb1000 when cold so might be an oil thing.
